Embodiment 1

[0015] The production technology of the trace element water-soluble fertilizer of embodiment 1 comprises the following steps:

[0016] S1: Add zinc sulfate heptahydrate, manganese sulfate monohydrate, copper sulfate pentahydrate, ferrous sulfate monohydrate, and chelating agent to the water in the reactor in sequence, heat up to 60°C, stir and keep warm for 2 hours, and cool to room temperature;

[0017] S2: sequentially add surfactant, borax and ammonium molybdate into the mixed solution obtained in S1 and stir until the solid material is completely dissolved;

[0018] The mass concentration of the trace elements zinc, manganese, boron, molybdenum, copper and iron in the trace element water-soluble fertilizer is 98g / L, and the surfactant is an anionic surfactant, and the consumption of the surfactant accounts for the total amount of the water-soluble fertilizer 0.2%.

[0019] Among them, the water-soluble fertilizer is an acidic fertilizer.

[0020] Among them, the concentr...

Embodiment 2

[0023] The production technology of the trace element water-soluble fertilizer of embodiment 2 comprises the following steps:

Abstract

The invention discloses a production technology of a trace element water-soluble fertilizer. The technology comprises the steps of chelating and uniform mixing. Copper, manganese, zinc and iron are chelated, and a surfactant, borax and ammonium molybdate are added to form a stable composite solution. The water-soluble fertilizer is sprayed on wheat, and has a substantial yield and income increase effect; and spraying of a foliar fertilizer has a law of the diminishing return, and the fertilizer efficiency of unit of a foliar fertilizer is reduced with the rising of the fertility of soil.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a production process of trace element water-soluble fertilizers. Background technique [0002] Crops absorb trace elements in the form of ions, and water is an indispensable carrier. In arid and semi-arid areas, even if water-retaining agents are used, the effect of root fertilization is still not high, while foliar spraying of water-soluble fertilizers has a better effect. Trace element water-soluble fertilizer is composed of one, several or all elements of copper, iron, manganese, zinc, boron and molybdenum, dissolved or diluted in water, used for irrigation and fertilization, foliar fertilization, soilless cultivation, soaking seeds For liquid or solid fertilizers for roots and other purposes, the key technical indicators for liquid and solid types in the standards for trace element water-soluble fertilizers are respectively trace element mass concentration ≥ 100g / L and mass fracti...
